Chapter 5: Biodiversity, Species Interactions, and
Population Control
|
Section 1: How Do Species Interact?
Concept 5-1: Five types of interactions among species--interspecific competition, predation, parasitism, mutualism, and commensalism--affect the resource use and population sizes of species. Section 2: How Do Communities and Ecosystems Respond to Changing Environmental Conditions?
Concept 5-2: The structure and species composition of communities and ecosystems change in response to changing environmental conditions through a process called ecological succession. |
Section 3: What Limits the Growth of Populations?
Concept 5-3: No population can grow indefinitely because of limitations on resources and because of competition among species for those resources. |
